I am definitely a 75 gal in the future, in a month or so probably... and there is time to cycle it and all. Okay, well, I have a 2 1/2 in. Gold Severum and I think he was getting ready to mate, even though he is the only Severum in the tank. He was moving gravel around in the back right corner of the tank, and when any of my Cories, or any other fish, came into the area of this, he scared them away. I looked up this behavior and it means establishing territory and he is ready to mate. Will this be a problem as one - there is no female to mate with and 2 - the tank is small and he claimed pretty much a good 1/4 of it to himself?
